Elijah Wentworth works in a research lab, teaching sign language to an orange-loving chimp named Eddie. Eli enjoys his friends-with-benefits relationship with Casey, but being a believer in fate and true love, he's unsure whether to settle or to hold out for something more. When Eddie starts signing poetry to Eli, Eli thinks Casey has trained the chimp to propose. It's time to make a decision: marry fun but flaky Casey or wait for the soul mate who might be closer than he thinks.
